The test methods in this standard are used to determine amount of certain metals that have the potential to be extracted from synthetic turf infill materials if ingested. The method is based on consumer safety specifications used to test the safety of children’s toys.
The standard calls for measuring mercury, lead, and other hazardous metal content in infill materials using EPA standards after a procedure that simulates the exposure of turf infill to stomach acid.
A sample of infill material is mixed with hydrochloric acid and, after prolonged agitation, the extract is analyzed via Microwave Plasma-Atomic Emission Spectrometer (MP-AES). The results are compared to EPA standards which provide maximum acceptable levels of antimony, arsenic, barium, cadmium, chromium, lead, mercury, and selenium.
